j The general object of my present invention is to provide improvedmeans for sup porting the load-carrying super-structure of a kiln carsuch as is used in tunnel kilns, and analogous industries. Morespecifically, the object of my invention is to provide an 1mprovedremovable supporting element, or post, for supporting the upper deck ordecks of a kiln car havingtwo or more decks on which. wareis carriedthrough a tunnel kiln for appropriate heat treatment. My 1111- provedsupporting post is made of fire clay or analogous material, and ischaracterlzed by its construction in separable parts so shaped that theeflective length of the post ma 7 be varied by a simple adjustment ofone of 1ts parts relative to the other.

The various features of novelty which characterize my invention arepointed out with particularity inthe claims annexed to and forming apart of this specification. For a better understanding of the invention,however, and the advantages possessed by it, reference should'be had tothe accompanying drawings and. descriptive matter in which I haveillustrated and described a preferred embodiment of the invention.

Of the drawings-:

Fig. '1 is an elevation partly in section showing my invention in use ona kiln car, Fig. 2 isan elevation of one form of post;

Fig. 3 is an. elevation partly in section of amodifiedtform withthecomponent parts separated; 6

Figs. 4, 5, and 6 arc v iews of other modified forms of cap pieces. 7

In the drawings is shown an open deck tunnel kilncar. A, having theusual wheels and supporting base and carrying three decks A, A and A,each consisting of a plurality of flat slabs of refractory material. Theupper decks are supported by vertical post elements B andD of variousforms and construction. Some of the supporting posts designated by theletter B may be of the usual hollow, cast fire clay type, while othersmay be ofthe adjustable form which is the subject of the presentinvention. i i

In Figs. 1 and 2 of the drawings is shown a simple form of adjustablepost D consisting of a base or body portion and a top or cap portion E.The body portion of the post D is of cast or pressed fire clay or othersuitable refractory material, and, as shown, is formed with an axialpassage D extending from its lower end upward for the greater part ofthe length of the post. At its upper end the part D is formed with anintegral cylindrical tenon-like extension D of reduced cross-section.The upper end surface of the annular portion of the base D surroundingthe base of the projection D. is of screw or cam form being formed, asshown, to provide two similar inclined surface portions or sections D?and D each extending half way aroundthe tenon D .The topor cap section Eof the post which may be made of the same. material as'the. body portionof. the post D,is formed with an axial passage or socket. E in its lowerend in which the tenon portion D of the body portion of the post D fitsand is rotatably received. The lowerend surface of the member E is screwor cam shaped, comprising sections E and E shaped similarly to, andcontacting with the surfaces D and D Theefl'ective lengthnof a postformed as described ofa part ,D and a part E maybe varied by rotatingone part relative to another. In Fig. 1, the adjustable post beneath theupper deck A is shown in its contracted form in which it doesnot engagethe deck A and, hence, may be readily removed and replaced preparatoryto, and at the respec tiveware unloading and loading operations.

The adjustable post D, shown as forming one of the supports for the cardeck A has its cap portion E rotated relative to the body portion. Tofacilitate. therelative rotation ofthe post sections to expanderincrease the length of the post sothat the latter will take itspropershare of the weight of the platform A, the two sections of thepostare shown as formed with holesE and D in which bars or likeimplements. may be inserted. The top and bottom section of each. adjustsable post may be positively secured in their adjusted positionby wedginga piece. of clay F or other material in the recess formed between theend of the cam portions as shown in Fig. 1. Ordinarily, the use of suchwedging material is unnecessary as the friction between the contactingsurfaces is usually sufficient to prevent the parts slipping from theiradjusted positions.

The form of postshown in Fig. 2 with'its spherical top does not providea large sur face'in co1i'tact'-\vitl1 the slab or deck portion wh'iclritengages and-supports. .Various ar= rangements are shown in Flgs. 3-6 bywhich the contact area is increased, and an even bearing surfaceprovided when the slab is not exactly at right angle's'td the post; Inthese Figs. 3 to 6 posts are shown as provid'ed'at their upper ends eachwith a" separate auxiliary cap piece or bearingmeinber ha'vin'gspherical contact" with an adj afcent surface of' the top: section. InFig; 3' the bearing member G'is" shown as'having a flat top portion Gand a' depending tenon Gr received in a cylindrical socket E in" theupper end'of the cap section EA and of slightly larger" diameter thanthe tenon G The tenon G is" forn'i'ed'with a spherical restinginac'oncave surface of greater di-' ameter formed'ln' the top ofthecapsectlon" EB of'th'e post. In Fig. 5 the bearingmembe'rG'Bisprovided'w'ith a concave recess G in its lower surface in which fits aconvex projection'bn the upper end .of the cap section'EG. InFi'g'.'6"the bearing" member GC is formed with a substantially sphericalknob projeetion'Gr engaging in a similarly shaped recess' in thetopsect'ionE'D. On the top surface of'ea chof the inembers'GB'and GCshown in Figs: 5' and6 are provided slightly spaced projections G forengaging the slab which" is supported by the member.

My improved posts with'their' self contained length adjusting provisionsare simple and effective. They are appreciably easier to install andadjust than the nonadjustab'le' post-s heretofore einployed'which havebeen securedinplace by separate wedge parts which are sometimes shakenout of place. In'fOIHKGYClGSigHS separate wedges were used to raise theposts. .These'wedges had a tendency toslip out of position when suddenlyjarred. In the present invention the we'dge is incorporated in the postitself;

hjilein' accordance with the provisions of" the statute's, I have"illustrated and" tie scribed the "best form of embodiment of myinventionnovv" known to me, it will be apparent" to thoseskilled intheart that changes may" lee made in the form OIE'iZhB apparatusdisclosed without departing from the spirit of my invention as set forthin the appended claims and that in some cases certain features of myinvention may be used to advantage without a corresponding use of wother features.

Having now described-my invention what I claim as new and desire" tosecure" by Let tersPatent is 1; A self containedadjustable decksupportingpost for akiln car formed of relatively axially movablerefractory parts to vary tl1e' 'effective length of said supportingpost.

2;" A decksupporting element for kiln cars comprising a base portion anda cap portion Ofi'efractOiy' material rotatably connected and adapted bytheir" relative rotation to vary the effective length of" saidsupporting elei'nentf 3'." A decksupporting element'for kiln carscomprising a basepo'rtion'a'nd a cap portion offrefractorv materialrotatably connected and adapted by their relative rotation to vary theeffective length of" said supporting element, and means for lioldingsaidportions in" the adj uste'd" position.

45. A deck supporting element for kiln cars coi'nprising a base sectionand a cap section of refractory material in rotatable engagement withone another and having contacting surfacesinclined'to their axes ofrelative rotation iwlierebythe height of said supporting element may bevaried when the sections are relativelyrotated.

5. A deck supporting element-for kiln cars comprising a base member ofrefractory material having a tenon-like projection at its upper end;cap-member of refractory material having a socket in'its lower end inwhicli'said projection is rotatablyreceived, said members havingcooperating inclined contact surfaces whereby the height of saidsupporting element may be varied byrotating said" cap member relative tosaid base member.
